SASH-LOCK.

SPECIFICATION forming' part 0f Letters Patent N 0. 671,921, dated April9, 1901.

Application filed December 10l 1900. Serial No. 39,287. (No model.)

To all whom it may concern:

Be it known that I, ABNER J UDsoN MOGE- HEE, a citizen of the UnitedStates, residing at Jackson, in the county of Madison and State ofTennessee, have invented certain new and useful Improvements inSash-Locks, of which the following is a specication, reference being hadtherein to the accompanying drawings.

The object of my invention is to provide a new and eifective lock whichwill secure both window-sashes in any desired position, preventing themfrom being raised -or lowered from the outside and also holding themtightly in the frame, so that they will not rattle.

The invention consists of the novel details of construction andarrangement of the parts, as hereinafter fully described and claimed.

Referring to the accompanying drawings, which form a part of thisspecification, similar characters of reference indicating, correspendingparts in all the views, Figure 1 is a horizontal section through thewindow-frame at the meeting-rails of the sash. Fig. 2 is a sectionalview of the complete lock and its key. Fig. 3 is a perspective view ofthe clamping-rod. Fig. 4 is a perspective view of the double-threadedrotating sleeve and clamp. Fig. 5 is the key adapted to engage thesleeve.

Referring to the drawings, A represents the lower sash; B, the uppersash; C C', the inner and outer facings of the frame; D D', the innerand outer stop-beads; E, the partingstrip, and F the window-jamie. Thelock is located in a recess in the jamb of the window in such a mannerthat the angled end l of rod G rests against the outside of the top sashand the clamp I against the inner side of the bottom sash, as shown inFig. 1.

The rod G has one end extended at right angles to form the clamp I, andthe other end has the right-hand threads 2. Sleeve H is fitted to rotatein the jamb of the window and has the right-hand threads 3 on its insideto engage the rod G and the left-hand threads on its outside to engagethe clamp I, which has left-hand threads in its aperture, and its end 5is provided with a square or angular hand threads 4, and the two sashesare thus clamped firmly against the parting stop E and are firmly heldagainst any effort to move them in any direction. When the sleeve isturned to the left, the clamps quickly recede from the sash and allowthem to move freely in the frame.

The key J has a long square or angular stem 6 iitted to the square orangular aperture 5 in the sleeve H, so that it will t up close to thewindow-facing when not in use, and may be drawn outward, so as to beeasily gripped in the hand,when it is desired to operate the lock.

This lock may be easily adjusted to any thickness of sash or frame byscrewing the sleeve H on or off of the rod G and the clamp I back andforth on the sleeve.

Having thus fully described my invention, I claim as new and desi-re tosecure by Letters Patent- A sash-lock comprising a rod angled at one endto form a clamp and threaded at the other end at such length as toenable it to be screwed some distance in or out of the sleeve, in orderto adjust the length of the lock to the distance from the outside of thetop sash to the inside of the window-facing, a tubular sleeve havingthreads on its inside reversehanded from the threads on its outside, athreaded clamp mounted on said sleeve, and a key having an angular steminserted into an angular aperture in the end of said sleeve, allsubstantially as and for the purposes specified.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in the presence of two Witnesses.

ABNER JUDSON MOGEHEE.
